I hope he is portrayed in a similar, but obviously opposite manner to that of Nolan's Bruce Wayne, intelligent, rich, well respected (at first) but with the resources to cause carnage.

a good story could be that he has good intentions (nuclear fusion in the wrong hands? perhaps, too similar to batman ofc but something like this) but with his lack of understanding of the world and those who inhabit it he puts us all in danger, could be a stark contrast to that of an "alien" who although isn't actually from here has a better idea of how to help us.

This could cause turmoil for Luther who cannot understand how an alien is able to better the world above himself, he is then outcast from the world and seeks to retake it in his vision.

would like to see Luther as intelligent too with everything in the world at his disposble, except ofc what it takes to be universally liked and accepted, much like what superman strives, and ultimately doesn't understand he is
